Explanation

The risk of eclamptic seizures does not resolve immediately after delivery; it persists into the postpartum period.
The highest incidence of postpartum eclampsia occurs within the first 48 hours after childbirth.
Clinical guidelines recognize this 48-hour window as the most critical period for monitoring and seizure prophylaxis.
While late postpartum eclampsia can occur, convulsions presenting more than 48 hours after delivery often prompt investigation into other neurological causes.

Option A: This is incorrect because the risk of convulsions is still very high immediately following delivery and during the subsequent hours.
Option B: This is incorrect. Although magnesium sulfate prophylaxis is often continued for 24 hours, the actual period of highest risk for seizures extends beyond this time.
Option C: This is an unsafe and incorrect timeframe. The risk for eclamptic seizures remains significant well beyond 12 hours postpartum.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Postpartum risk period for eclampsia as background academic context rather than a clinical decision trigger.
Nurses must maintain vigilant monitoring of postpartum patients with pre-eclampsia for at least 48 hours, assessing for headache, visual changes, epigastric pain, and elevated blood pressure.
Patient education upon discharge is critical. The patient and her family must be taught the warning signs of postpartum pre-eclampsia and instructed to seek immediate medical attention if they occur.
What if? If a patient develops a new-onset seizure 72 hours postpartum, it is considered late postpartum eclampsia. While treatment for eclampsia should be initiated, the healthcare team must also urgently investigate other potential causes, such as stroke, epilepsy, or cerebral venous thrombosis, as this timing is less typical for eclampsia.

How to Approach the Question

First, identify the core of the question: it asks for the time frame when the danger of convulsions from pre-eclampsia ends after delivery.
Recognize the keywords: 'convulsion', 'pre-eclamptic toxaemia', 'danger ends', 'after delivery'.
This is a factual recall question based on established clinical knowledge and guidelines in obstetrics.
Recall that pre-eclampsia is a systemic disease, and its effects, including the risk of seizures, do not cease immediately with delivery.
Evaluate the given timeframes. Eliminate the shorter durations (soon after, 12 hours, 24 hours) as they fall within the known high-risk period.
Select the option that represents the standard end of the most acute risk period, which is widely accepted to be 48 hours postpartum.
